Nonlinear magnetoelectric effects in flexible composite ferromagnetic – Piezopolymer structures

Nonlinear magnetoelectric (ME) effects in a flexible composite planar structure, containing mechanically coupled layers of amorphous FeBSiC ferromagnet and PVDF piezoelectric polymer have been experimentally investigated. Under the action of a weak harmonic magnetic field h with frequency f = 50–1000 Hz and tangential bias magnetic field H = 1–80 Oe, the structure generated a voltage of the same frequency. The efficiency of linear ME conversion...
